A hacker is someone who likes to tinker with electronics or computer systems. Hackers like to
explore and learn how computer systems work, finding ways to make them do what they do better, or
do things they weren’t intended to do. There are two types of hackers:
White Hat – These are considered the good guys. White hat hackers don’t use their skills for illegal
purposes. They usually become Computer Security experts and help protect people from the Black
Hats. Black Hat– These are considered the bad guys. Black hat hackers usually use their skills
maliciously for personal gain. They are the people that hack banks, steal credit cards, and deface
websites.
These two terms came from the old western movies where the good guys wore white hats and the bad
guys wore black hats.
